SPECIPICATION iorming part of Letters Patent No. 315,306,dated April 7,1885.

Application filed February 5, 1885. (No model.) i

.To aZZ whom it may concerrt:

Be it known that I, WILLIAM LOVE, a citizen of the United States,residing at Port Huron, St. Clair County, and State of Michigan, haveinvented a Feed-VVater Heater; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvenents in water-heaters for steam-boilers;and the objects of my improvements are, first, to so locate theheater-pipes with relation to the fire as to impart the greatestpossible amount of heat to the water in said pipesconsistent with theother objects of my improvements; second, to utilize said pipes forsustainng the arch of the smoke-box, and, third, to so construct andarrange said pipes as to enable the operator to clean them at willwithout taking them apart or disturbing the brick-work of the smoke-box.I attain these obj ects by the mechanism illustrated in the accompanyingdrawings, forming a part of this specification, in which- Figure l is aside elevation of the smoke-box located at the rear end of the boiler,with the brick walls partly removed to show the arrangement ot' theheater-pipes, and Fig. 2 is a top or plan view of the said pipes on theline x w of Fig. 1, with the arch or roof of the smoke-box removed. I

The same letters of reference refer to corresponding parts in both thefigures.

The boiler A is constructed-in the nsual manner, with fiues extendingthrough the same for the passage of heat and the products of combustion,the rear end only being shown. It rests on brick-work B, constructed inthe usual manner, the furnace (not shown) being located under the frontend of the boiler. The products of combustion pass under the boilerthrough the passage Cthe entire length thereof, thence into thesmoke-box D, and return through the return-flues located within theboiler to the smoke-stack at the front end. It is obvious, however, thatany other form of boiler may be used-as, for instance, thelocomotive-boiler commonly used with portable engines where the productsof conbustion pass directly through the flues to the smokestack at therear end.

i The heater consists of the pipes E, located in the upper part of thesmoke-box D, and are connected together by transverse pipes F. Thesepipes are held to the boiler by resting on brackets G, or in any othersuitable manner, and serve to sustain the root' or arch of thesmoke-box. The vertical pipes H and the horizontal pipes I serve toconvey the heated water from the heater-pipes proper to the boiler atI'. There are twoof these passages, one connected to each of the outsidepipes, E, of the series. verse connecting-pipes F, the vertical pipes H,and the horizontal pipes I are extended each pipe is .fitted with aremovable cap, C', to enable the operator to clean the whole seto do so;The series of pipes E are usually and just above the upper. row of fiuesin the boiler; but it is obviou's that they may be placed partiallyabove and partially below the water-line, in which case aconnecting-pipe should lead from the upper side of one or more of thepipes to the steam-space in the boiler, as shown in dotted lines, inorder to Convey the steam found in the pipes direct to the boiler, thusequalizing the pressure and ob- Viating the liability to force all thewater out them; The water is fed to the pipes E through the pipe J,having a regulatng-cocl, K. It is obvious, however, that it maybe fed atany of my invention. in the arrangement of the pipes, not only inreference to the point at which they are fed, but with reference tothecourse which the water takes after enterin g the pipes. I thereforeapparatus here shown; but,

Having fully described my invention, what I of a series of horizontalpipes arranged in the top of the smoke-box and supporting the archthereof with the boiler and the connectingpipes, substantially as andfor the purpose described.

Each of the pipes E, the transthrough the walls and roof of thesmoke-box, i and terminate outside thereof, and the end of claim anddesire to secure by Letters Patent,`

ries of pipes whenever it becomes necessary located just below thewater-line of the boiler of the pipes by the steam generated withinother point without departing from the spirit Modifioations may be madedo not limit myself to the particular form of i 1. In a feed-waterheater, the conbination i 3\ 1 t Ico 2. In a feed-Water heater, thecombination of the boiler with a series of horizontal pipes arranged inthe top of the smoke-box and having their ends projeoting therefrom, andeach provided With a removable cap, substantially as and for thepurposeset fo'th.

In a feed-water heater, the oombination of the boiler With a seriesof horizontal pipes and Vertical oonnecting-pipes located in thesmoke-box, each of said pipes having one or IO both of its ends prejeotng through the outside of said smokebox, said projecting ends beingprovided With removable Caps, substantially as and for the purposedescribed.
